ELECOM has begun selling wired earphones with 3.5mm mini plugs in late July[1]. The lineup covers open inner-ear designs and sealed canal designs, each offered with and without a microphone, for four series in total. Counting color variations, that comes to 16 model numbers. Pricing is open, meaning retailers set the street price. Even with true wireless dominating the category, there is still an audience that wants earphones which need no charging and no pairing, and this lineup aims squarely at that group.

Plug In and Go

All four series share the same basic promise: plug them into a smartphone, tablet, or PC with a 3.5mm mini jack and they work[1]. There is no battery level to watch and no pairing step. The familiar true wireless problem of discovering a dead earbud right before a meeting simply does not apply.

The cable is a Y-type measuring roughly 1.2 meters, a length that works both at a desk and when running down to a phone in a pocket[2]. Frequency response spans 20Hz to 20,000Hz and maximum input is 10mW across every series[2][3].

One caveat: these will not work on devices without a 3.5mm mini jack. Since many recent smartphones have dropped the headphone jack, buyers may need a separate USB Type-C or Lightning adapter[1].

Open Inner-Ear Versus Sealed Canal

The EHP-F14IA inner-ear series rests at the entrance of the ear canal in an open design. It puts less pressure on the ear during long sessions and lets ambient sound through naturally[1]. It uses a large 14.2mm driver, has an impedance of 21 ohms, and weighs about 2.4 grams per side excluding the cable[2]. Colors are black, dusty blue, pink greige, and white[2].

The EHP-F15CA canal series seals the ear canal like an earplug. It leaks less sound and isolates better, which suits listeners who want to sink into the music[1]. The driver measures 10mm, impedance is 16 ohms, and each side weighs about 1.9 grams, lighter still than the inner-ear model[3]. Three eartip sizes ship in the box, S, M, and L, with M pre-installed[3]. Colors are black, white, rose gold, and lilac[3].

The two designs split cleanly by use case. Inner-ear suits working from home or moving around outdoors, where you want to hear what is going on. Canal suits focused work or watching video somewhere quiet.

Microphone Models Handle Calls and Voice Assistants

The microphone versions are the EHP-F16IM inner-ear series and the EHP-F17CM canal series. Both connect through a 4-pole 3.5mm mini plug and handle voice calls alongside music[1].

A center button on the inline remote answers and ends calls, and a long press summons the voice assistant without taking the phone out of a pocket[1]. There is a limit worth knowing about: the answer and end-call functions do not work with internet calling apps such as Microsoft Teams. Behavior can also vary by device and app, so anyone buying primarily for calls should check compatibility with their own setup[1].

Cable Durability and Reworked Packaging

Broken cables are the most common failure point for wired earphones. All four series use what ELECOM calls a reinforced cable design, which the company says passed durability testing based on its own measurement standards[1]. Cheap wired earphones often fail at the strain relief, so attention here has practical value.

On the environmental side, the products qualify for THINK ECOLOGY, ELECOM's in-house certification mark. The outer box is designed for shipping efficiency, packaging uses only paper, cardboard, and poly bags, and plastic weight is reduced by more than 20 percent compared with the company's internal baseline products[2]. Operating conditions run from minus 20 to 65 degrees Celsius and 20 to 80 percent relative humidity, with a one-year warranty[2][3].

Summary

ELECOM's 3.5mm wired earphone lineup consists of four series and 16 model numbers: the open inner-ear EHP-F14IA, the sealed canal EHP-F15CA, and their microphone-equipped counterparts, the EHP-F16IM and EHP-F17CM. Between the two driver sizes of 14.2mm and 10mm, the reinforced cable design, and remote controls that handle calls and voice assistants, the range covers what buyers actually ask of wired earphones. As a backup pair that needs no charging or pairing, or as the everyday choice for devices that still have a headphone jack, it is an easy option to reach for.
